Answer:
0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-7)/(8-0)
m=0/8=0
Attached the solution with work shown.
Answer:
-3
Step-by-step explanation:
First step to this is to replace the variables with their coordinated values. Remember to use parentheses.
4(2)-2(2+4)+1=?
We can start to simplify.
4(2)-2(6)+1
Then---
8-12+1
-4+1
Final Answer (-3)
Answer:
(-21,-19)
![\sqrt{849}](https://tex.z-dn.net/?f=%5Csqrt%7B849%7D)
Standard form
Step-by-step explanation:
We are given the equation of circle
![x^2+y^2+42x+38y-47=0](https://tex.z-dn.net/?f=x%5E2%2By%5E2%2B42x%2B38y-47%3D0)
General equation of circle:
![x^2+y^2+2gx+2fy+c=0](https://tex.z-dn.net/?f=x%5E2%2By%5E2%2B2gx%2B2fy%2Bc%3D0)
Centre: (-g,-f)
Radius: ![\sqrt{g^2+f^2-c}](https://tex.z-dn.net/?f=%5Csqrt%7Bg%5E2%2Bf%5E2-c%7D)
Compare the equation to find f, g and c from the equation
![g\rightarrow 21](https://tex.z-dn.net/?f=g%5Crightarrow%2021)
![f\rightarrow 19](https://tex.z-dn.net/?f=f%5Crightarrow%2019)
![c\rightarrow -47](https://tex.z-dn.net/?f=c%5Crightarrow%20-47)
Centre: (-21,-19)
Radius (r) ![=\sqrt{21^2+19^2+47}=\sqrt{849}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B21%5E2%2B19%5E2%2B47%7D%3D%5Csqrt%7B849%7D)
Standard form of circle:
![(x+21)^2+(y+19)^2=849](https://tex.z-dn.net/?f=%28x%2B21%29%5E2%2B%28y%2B19%29%5E2%3D849)
The centre of circle at the point (-21,-19) and its radius is
.
The general form of the equation of a circle that has the same radius as the above circle is standard form.
2 flowers are 5.5 feet tall and 4 are 7 feet tall, you subtract 2 from 4 and get 2.
2 flowers is the answer.
